Type Checking

Expected Behaviour

When assigning a class/key-value table to a type defined as an array, a diagnostics error should be raised.

Actual Behaviour

No diagnostics error is raised.

Reproduction steps

local dict = {a = 'a'}

---@type number[]
local array = dict

Observe that no diagnostics error is raised when assigning dict to array, which is defined as an array.

Additional Notes

lua-langauge-server should check for the presence of non-integer indices in a table. If there are any, the table should not match the array type.

I believe the present issue is the underlying issue in #1721.

Version

3.13.6-1

该 issue 未指定源文件或测试。首先使用 lua-language-server 3.13.6-1 运行提供的 Lua 复现，并跟踪 table-to-array 赋值的类型检查路径。当包含非整数键的表触发 diagnostic，而有效数组仍被接受时，即表示完成。
